To avoid unnecessary link retraining when the panel is in Replay/PSR mode,

amdgpu_gem_align_pitch() is passed u32 width and cpp from dumb buffer
creation but uses signed int internally. The round-up add and the
aligned * cpp multiplication can overflow, returning zero or a negative
pitch. A zero pitch propagates to a zero-sized GEM object allocation
that reaches userspace via DRM_IOCTL_MODE_CREATE_DUMB.
Switch the helper to unsigned int and use check_add_overflow() /
check_mul_overflow() so wraparound returns zero. Reject a zero pitch
or size in amdgpu_mode_dumb_create() rather than allocating a zero-
byte BO.

It's possible that some sdma instances aren't working so we shouldn't try
to use them from TTM. To achieve this, delay the call to
amdgpu_sdma_set_buffer_funcs_scheds after the rings have been tested, and
then use the 'ready' property to decide if a sched should be used or not.
Note that currently it's not doing much, because if the ring helper fails

This will allow the use of all of them for clear/fill buffer
operations.
Since drm_sched_entity_init requires a scheduler array, we
store schedulers rather than rings. For the few places that need
access to a ring, we can get it from the sched using container_of.
Since the code is the same for all sdma versions, add a new
helper amdgpu_sdma_set_buffer_funcs_scheds to set buffer_funcs_scheds
based on the number of sdma instances.
Note: the new sched array is identical to the amdgpu_vm_manager one.

amdgpu_userq_wait_ioctl() takes extra references on waited-on fence
drivers and stores them in waitq->fence_drv_xa. When a new userq fence is
created, those references are transferred into userq_fence->fence_drv_array
so they can be released when the fence completes.
However, those inherited references are currently only dropped from
amdgpu_userq_fence_driver_process(). If a fence never reaches that path,
such as it is already signaled when created, so we need to explicitly release
those fences in that case.
